Add parameters to set the origin of the excision region for "fixed

excision".

When checking for (real-valued) mask values, do not check for
equality, but instead allow for a fudge factor.

Check that the thorn is activated when any of its routines are called.

When there is only a single point excised, do not abort with an
internal error, but pretend the normal extends into the x direction.
